Tom said there are State laws regarding betterments and taxes and there is not much flexibility. Nate said with Home rule, anything is possible, starting with the Board of Health which is a powerful body. Title 5 was not envisioned to protect estuaries. Usually homeowners do not want to handle their own waste and if it is not properly managed, nitrogen will still go into the ground. There is concern for potential for disease-it could be a serious health threat. Incinerating toilet, en masse create odors and are considered an impractical solution. Tom wondered if requiring all homeowners to have a composting toilet is enforceable-it would have to be voluntary. Where does that nitrogen go? Brian Howes added that incinerating toilet use a lot of fuel. Park service uses them in remote locations. There is an odor issue. It is not a panacea. There is liquid waste to dispose of. S&W can determine a cost of all household to use composting toilets. Ken Malloy asked for clarification on scope of scenario. Tom said they will not be based on timing but based on meeting the ultimate target. The first round will not include costs, those will be refined to 2-3 scenarios which will include costs. John Fitz, homeowner in Mashpee. He is has been working on a wastewater treatment system for years and it is now completely design and assembled; will be tested in June and July. He described how it works. Will be seeking permitting in July. He suggested the members visit the test site which is in Mashpee. He has been working with G Heufelder at the County and will provide him with results. Ed Baker asked: - will we run scenarios to build out? Yes - will there be a defined value going back into the ground/discharged?Yes - he would like to see the work done by subwatersheds instead of priority areas and planning zones which seems to be the way it is going. Ken Malloy asked why costs will not be associated with first scenarios? Cost should come into the equation as soon as possible. Tom Cambararie, Cape Cod Commission, congratulated the sewer commission on their work to date. Use of MEP data is exciting. This is cutting edge work which will be replicated elsewhere on the Cape. Requires an identifiable process to identify the scenarios. He offered the assistance of the Commission's water resources department to condense down some of the numerous permutations. Ed Baker thought they would run the model only for the best scenario and those results would tell you where you had to adjust-it would be a series of model runs not in parrallel. Jeff explained the commission will choose 5 scenarios and a model will be run for each, in parallel for the first round. Tom said it will be dependent on the commissioners' and engineers'judgment. Tom Fudala's initial list of ideas for scenarios: 1. a. Traditional sewer system using treatment plants, ignoring use of existing private system b. Focus on use of existing systems and expand them. Large section of top priority areas are already sewered. 2. Nitrex technology 5
